Description

Technical Field

[0001] The present invention relates to the technical field of steam ovens, and in particular to a gas-liquid partitioning device and a steam oven. Background Art

[0002] The steam ovens currently in use all have an air duct on the top of the cavity, and then a cooling fan is used to force air to blow outward, so that the gas in the cavity is blown out from the pipe through the air duct. Since the gas is blown out directly through the air duct at a faster speed, the heat dissipation of the gas in the air duct is less. Therefore, when discharged to the outside of the machine, the temperature of the discharged gas is still very high. Moreover, in the existing design, the higher temperature water vapor in the cavity will also be blown out from the gap between the control panel and the door assembly of the steam oven toward the front side of the oven door of the steam oven. If the steam oven is installed at the bottom of the stove, the user's feet will be blown by the higher temperature hot air, and the discharged hot air may easily scald the human body, affecting the user experience. In order to avoid the above situation, the specific installation location of the steam oven will be limited, affecting the user's independent choice.

[0003] The existing structure also has the problem that some condensed water will condense during the blowing process and fall back into the cavity along the air outlet, affecting the taste of food and the operating efficiency of the machine. In addition, when the steaming function of the steam oven is turned on, more water vapor is generated in the cavity. When it is blown out of the machine, it has not reached the condensation temperature. When it encounters objects with lower temperatures outside, it is easy to condense into water droplets. After the gas is blown out, it condenses, and it is difficult to recover the condensed water. It will also make the surrounding environment humid and even form water accumulation.

[0004] Finally, the gases generated in the steaming and baking cavity of the steam oven include water vapor and smoke. After the smoke with a relatively large proportion of oil smoke and the water vapor mainly composed of water generated in different cooking modes enter the above-mentioned air duct from the cavity of the steam oven, the cooling fan forces convection to mix and blow them out, and the water vapor and smoke are discharged from the same pipe, resulting in condensation water containing oil pollution, water vapor and smoke mixed and blown out, and even backflow into the cavity to cause odor.

[0042] refer to Fig. 9 , Fig.10 and Fig.13 In a preferred embodiment, the condensation member 9 includes a fixed plate 90, the fixed plate 90 includes a first surface in contact with the upper chamber 7 and a second surface in contact with the lower chamber 8, a first row of plates 91 is arranged on the first surface of the fixed plate, the fixed plate 90 and the first row of plates 91 cut the space of the upper chamber 7 into a plurality of parallel straight gas paths 12, the straight gas paths 12 are connected to the first through hole 170, the straight gas paths 12 are composed of a plurality of mutually parallel channels, an auxiliary blowing device 21 is arranged at the first end of the straight path 12, the second end of the straight path 12 is connected to the outlet gas 5, a second row of plates 92 is arranged on the second surface of the fixed plate 90, the fixed plate 90 and the second row of plates 92 cut the space of the lower chamber 8 into a serpentine gas path 13, the inlet of the serpentine gas path 13 is the second through hole 180, and the outlet of the serpentine gas path 13 is connected to the outlet gas 5. Multiple vertical grooves are arranged on both sides of the condensation member 9 to increase the surface area. One side of the vertical groove is set as a serpentine opening (the side of the condensation element 9 close to the lower condensation chamber), which increases the passage and contact surface of the steam recondensation element 9, and fully contacts and dissipates heat. The other side is an upright structure (the side of the condensation element 9 close to the upper condensation chamber), which increases the surface area while allowing the cold air of the cooling fan to pass quickly and take away the heat on the condensation element 9. The condensation element 9 is installed on the air duct seat, and the air duct formed by the air duct cover and the air duct seat is divided to separate the cavity steam and the cooling gas blown out by the cooling fan. At the same time, the steam condensation and flue gas cooling are divided into two different upper and lower channels.

[0043] refer to Fig. 9 , Fig.10 and Fig.13In a preferred embodiment, a conducting hole 22 for connecting the lower cavity 8 and the air outlet 5 is provided between the air duct seat 2 and the fixing plate 90. The conducting hole 22 is located at the outlet of the serpentine air path, and the serpentine air path is connected to the outlet air through the conducting hole. Optionally, the conducting hole 22 is provided on the fixing plate of the condensing member 9. When there are two serpentine air paths 13, two conducting holes 22 are also provided on the fixing plate 90 of the condensing member 9.

[0044] In a preferred embodiment, the auxiliary blowing device 21 is a fan or an air pump.

[0045] In a preferred embodiment, the driving device 10 is a synchronous motor, and the lower chamber is connected to a liquid recovery box.

[0046] refer to Figure 3 and Figure 4 The steam oven includes a steam oven body 24 and the gas-liquid partitioning device. The seat 1 is installed on the steam oven body 24. A steam oven cavity is provided in the steam oven body 24. The steam oven cavity is connected to the air inlet 4 through a first pipe. The condensed water recovered in the lower cavity can be transported to the steam oven cavity through a second pipe for reuse. The seat 1 provides a bearing function. The seat 1 is installed on the top of the steam oven body 24 and is connected to the exhaust pipe on the cavity of the steam oven body 24 through the air inlet 4. The water droplets condensed by the condenser are collected and flowed out from the water outlet pipe of the air duct seat for recovery.

[0047] Technical principle: The electronic control program divides the functional modes of the steam oven with steam and without steam into two categories, and matches them respectively: when the second micro switch 20 corresponding to the steam function is triggered, the synchronous motor stops rotating; when the first micro switch 19 is triggered for the mode without steam function, the synchronous motor stops rotating.

[0048] When the steam menu working mode is started, the synchronous motor drives the valve core 15 to rotate through the transmission member 16. When the second toggle rod 162 contacts the second micro switch 20, the synchronous motor stops rotating, the bottom exhaust port of the reversing valve is in the open position, and the top exhaust port is in the closed position. The steam enters the bottom condensation chamber from the bottom exhaust port. At this time, the steam can only be discharged from the serpentine route set by the condenser. The process fully contacts the inner wall of the condenser, quickly cools down, becomes low-temperature steam, and generates condensed water. The condensed water is collected and flows to the condensate recovery pipe for recycling. The low-temperature dehydrated gas is discharged from the opening at the end of the serpentine route into the air duct. At the same time, the groove on the upper part of the condenser is quickly cooled by the cold air from the cooling fan, so that the temperature of the entire condenser will not be too high, and the steam at the bottom can be condensed better. Finally, the upper and lower gases are collected from the outlet of the condenser, and the forced discharge formed by the air duct seat and the air duct cover completes the entire condensation recovery effect.

[0049] When the menu without steam mode is started, the synchronous motor drives the valve core 15 to continue to rotate through the transmission member 16. When the first toggle rod 161 contacts the first micro switch 19, the synchronous motor stops rotating, the top exhaust port of the reversing valve is in the open position, and the bottom exhaust port is in the closed position, and the smoke is directly blown out by the cooling fan from the top exhaust port.

[0050] Through the above actions, a condensation channel for steam and a heat dissipation channel for flue gas can be realized without interfering with each other; the steam condensation chamber is relatively independent, and the condensed water is free of oil fume pollution and odor.
